– 40Gbps M.2 NVMe SSD Enclosure with Cooling Fan Aluminum

Very effective and high quality ssd enclosure. it is very well made, easy to set up with whatever SSD you have. It has a metal body and ventilation ports with the addition of a quiet switchable fan: so temperature control should not prove a problem. It is future proof in spec and although not cheap I feel offers very good long term use at a reasonable cost.

This is a great external drive housing for a Mac Mini. Its Thunderbolt 4 connector means that it performs really well. Not quite as fast as the internal SSD but pretty close. It comes with a Thunderbolt 4 cable which is well constructed. Fitting the SSD was simple and took a few seconds. The case is metal and solid - it will survive the rigours of travel. My only criticism is that the fan needs to be switched on or off using a button. I would much rather that the fan is triggered when the SSD temperature goes above a certain level. I found the fan to be a little noisy but it is not far from me and it may be less intrusive in other setups.

Excellent enclosure - easy assembly, speed is excellent - around 3100MB/2900MB R/W. Temperatures have been great even WITHOUT turning on the inbuilt fan (when mac is under GPU load running LLM related workload - see screenshot): SMART/Health Information (NVMe Log 0x02, NSID 0xffffffff) Critical Warning: 0x00 Temperature: 32 Celsius Available Spare: 100% Available Spare Threshold: 10% Percentage Used: 0% Data Units Read: 1,977,041 [1.01 TB] Data Units Written: 1,804,176 [923 GB] Host Read Commands: 20,136,510 Host Write Commands: 14,040,961 Controller Busy Time: 230 Power Cycles: 52 Power On Hours: 59 Unsafe Shutdowns: 4 Media and Data Integrity Errors: 0 Error Information Log Entries: 0 Warning Comp.

This is a fantastic item, it’s reasonably small in size and the build quality is superb, light alloy with a switchable cooling fan that is hardly audible, I fitted this with a 2TB Samsung NVME 990 pro drive, and attached this to my Mac mini m1 and set it up to be the boot drive, this runs perfectly. I am getting faster speeds from this drive than I am getting from my Mac M1’s built in ssd hard drive. File transfers are so fast. It has never overheated even under continuous loads. I will be purchasing a second one in the future and have no hesitation in recommending it.

What a brilliant little device this is. So easy to use, and unlike my previous enclosure I tried, it just gets warm. Truly ‘tool free’ to put your NVMe chip in, use the rubber stopper and apply the thermal tape. Clip on the cover and you are good to go. There is a push button switch that turns the fan on and off. When the fan is running it’s very quiet, and very efficient at cooling. I leave the fan off and it is just warm. Perhaps under heavy data use the fan would be required. If I had to complain about one thing, the fan could be temperature controlled? Fully recommend this enclosure. I used a Samsung 990 Pro 2TB NVMe chip.

Needed some extra hard drive space without paying the Apple Tax on SSD so after researching wnet for this along with a 4TB Crucial P3 stick of SSD. I'm getting about 1400MB/s write and 2100MB/s read, and I was hoping for more in the region of just over 2000MB/s write, consdering the set up and via Thunderbolt 4. However, it may well be due to it being plugged into a Caldigit TS4 dock and also having a Thunderbolt 3 monitor attached as well as numorous other hardware attached to it, which is bound to reduce the bandwith, but that still appears to be slow. Strangely when I look at the system report, it is connecting at Thunderbolt 3 speeds. I am going to change things around to see if I can improve those speeds by plugging direct into the MacBook, which I have tried before, but still not getting the speeds I expected. As for putting it together, that was a breeze. From unboxing to up and running was 5 - 10 minutes max and I have had no issues withoverheating, with the fan being on most of the time, you dont really notice that much noise. It was stilll a cost effective way to add SSD to the Mac and in farness, even the speeds I am geting now is fine for what I am using it for, mainly for FCP and theres been no issues yet, but be good to improve them. Price for the enclosure was also good, on offer at the time, which often happens, look for those vouchers and the build is good, nice and sturdy, though it can possibly be a bit to eay for the top to become loose, but I dont plan on using it as a portable drive but more of a permenant fixture with the dock. I'm 75% happy with it, though if I was building anoter one, which i probably will, I'd probably try a different brand just for comparision of speed.

I needed an SSD for video editing (to save were and tear on my laptop's internal drive). I paired this with a WD 2TB NVMe SSD and it flies. It's plugged into a TB4 port on my Caldigit TS4 and, whilst not as fast (according to the Blackmagic speed tester) as my MacBook's internal SSD, it's running at full Thunderbolt 4 capacity. No more stuttering when editing video (something I was starting to get with my Samsung T7). This enclosure has the advantage of a switchable fan - not needed most of the time and I only click it on when transferring large files to it, and when rendering final video (as that seems to be when it gets hot) - the solid aluminium box is plenty of heat sink for more normal use.

Excellent quality and great speed. Speeds are as advertised but will vary depending on the SSD drive of course. Great build and quality. Well worth it

Su acabado es excelente , todo en aluminio, como indica ,no necesita herramientas para la instalación de la memoria. Todo se hace de forma sencilla y funciona eficazmente. He comprado un cable Thunderbolt 5 para garantizar la estabilidad de la transferencia de datos, (pues había leído que en algunos circunstancias, el cable que viene no garantizaba estabilidad, pero no he llegado a probarlo) , de momento solo puedo hablar maravillas . Velocidades muy rápidas apenas genera ruido y de momento en mi experiencia no se calienta apenas , tiene un ventilador incorporado que puedes conectar o desconectar que genera un poquito de ruido, pero yo no he tenido que usarlo. De momento muy satisfecho con la compra. Lo estoy usando con una memoria de Samsung la 990 evo plus de 4TB

Utilisé avec mon MacBook Air M1 pour du montage video, je profite de débit beaucoup plus rapides qu’avec mon Samsung T7. (Pratiquement 3000 en lecture / écriture avec un M2 Samsung 990 Evo Plus de 2To). D’après ce que j’ai compris, ça pourrait être plus rapide, mais c’est dû au contrôleur de la puce M1. Cependant, c’est largement assez rapide pour travailler sur Final Cut avec de « gros rushs », sans ralentissement (ce qui arrivait de temps en temps avec le T7). Je n’ai pas du tout remarqué que le boîtier chauffait fort, à tel point que je ne sens pas l’utilité d’allumer le ventilateur. Ce dernier fait un petit peu de bruit, mais il suffit de l’éloigner avec le cable plutôt long (par exemple le placer derrière votre écran) et le bruit devient vraiment très faible. Pour moi qui déteste les bruits de soufflerie et qui aime travailler dans le silence total, ce n’est pas vraiment gênant (surtout quand on fait du montage video, puisqu’on va forcément entendre du son des rushs). C’est donc un bon produit, peut-être un peu cher quand même à l’heure où le Thunderbolt 5 arrive, mais ça reste quand même intéressant quand on voit le prix du stockage chez Apple ou chez des vendeurs de SSD externe qui propose du Thunderbolt…
